Since i switched from my s10e to my s25, the battery on my og galaxy watch 1 42mm has gone from 4 days to 1.5. I cant find anything in my settings that is diffrent to make this much of a drop in battery life. I looked at upgrading to a watch 6 or 7 but the battery life isnt much if any better on them from what i have now. I mainly use the watch for time, and notifications to see if its something i need to answer now or leave my phone in my pocket.
@Junyer357 Samsung is ending support for watches using the Tizen OS like your OG GW1. So there may be communication between the phone and watch which is failing and retrying multiple times. That could be the reason for reduced battery life on your watch.
If you want your watch to continue to work with your Samsung phone, you will have to face the reality that those watches are dead and you need to buy a newer model. They have lived a good life and now must retire. I'm actually surprised they lasted this long.
No it sounds like samsung is actively killing it since it was a good product and works well enough it keeps folks from needing to upgrade. 3 weeks ago i had 4 full days of bettery life with my old phone. So something on the s25 is intentionally killing it.
That's because they *are* actively killing it. They announced the end of Tizen support last year. The end of Tizen support will be September 2025. Tizen is an outdated operating system, and the old watches cannot be updated to WearOS. Tizen is no longer compatible with the newer Android or OneUI versions. Nothing is forever. Those watches have outdated hardware and operating systems. You can still use it as an unconnected watch, or on an older phone; but if you keep it connected to a newer phone, not only will most features not work, your battery will work harder to try to get those features to work. That is why your battery life is going downhill. You can probably get a decent trade in value for it toward a new model.
